Wheelock’s Series MB Motor Bells provide a better-engineered motor bell for fire and life safety alarm systems. The Wheelock Series MB Bells include higher dBA, low current draw, built-in trimplate for semi-flush mounting, low frequency aluminum shells, and low RFI noise. The motor for Series MB Bells is a durable, high-torque permanent magnet motor selected for its high performance and long life.
These DC vibrating Series MB Motor Bells are offered in 6” and 10” shell sizes in both 12 and 24 VDC models.
Series RSSP Sync/Non-Sync retrofit plates are used in conjunction with the Series MB Motor Bell when combination appliances are required. The Series RSSP retrofit plates are available with either Multi-Candela or single candela strobes and easily mount to a 4” square or Wheelock SBL-2 backbox. All Series RSSP strobe appliances meet or exceed the requirements of NFPA 72 (National Fire Alarm Code), ANSI 117.1 (American National Standard for Accessible and Usable Buildings and Facilities), ADA (Americans with Disabilities Act) and UL Standard 1971 (Signaling Devices for the Hearing Impaired).
The Series RSSP retrofit plates may be synchronized when installed with the Wheelock Series SM, DSM, Sync Modules or the PS-12/24-8CP or PS-12/24-8MP Power Supply with Wheelock’s patented sync protocol. Wheelock’s synchronized strobes offer an easy way to comply with ADA requirements concerning photosensitive epilepsy.
Note: The MB Series Bells are available in Red (R) or Gray (S). Ordering the Gray (S) option may delay your order by up to 5 days.
